Women who are breastfeeding may be looking for safe and effective forms of contraception. Before using a certain birth control method, it is important to make sure it is not going to affect breast milk production or cause other problems.
For example, it is not usually recommended for women to use estrogen within the four weeks after childbirth, as it can increase their risk for a serious blood clot. Also, estrogen can decrease breast milk production. Therefore, if a woman is looking to use a hormonal form of contraception while breastfeeding, a progestin-only product is usually recommended.
Other forms of contraception safe for use while breastfeeding include nonhormonal methods, such as condoms, cervical caps, and diaphragms. There are also natural methods, such as the rhythm method and the lactational amenorrhea method (LAM).
